عنوان مقاله [English]
In this paper, a new method is presented to simplify the pull down tree in DCVS logic, using a new levels coupling rule. This
rule, which is introduced in this article, can provide more reduction possibility. The proposed algorithm introduces a new approach
for the DCVS tree network design by making use of this rule and its combination with former rules. A matrix description is used for
the first time, for describing the relation between the order of inputs and control variables in the decision diagram. By applying
this method, one can achieve a remarkable improvement, in terms of speed and chip area. The simulation comparison of applying
this algorithm to some standard benchmark circuits demonstrates a significant reduction in the number of nodes involved.
